HVLP guns need air. The 1/4" quick couplers do not flow air well. The 3/8" couplers flow twice the air. The problem with the smaller coupler is that you start out with higher pressure and since the couplers can not flow the air you get a drop off of pressure. You have to change your rate of movement to compensate and that is not easy to figure out when you are just starting out. | HVLP guns need air. The 1/4" quick couplers do not flow air well.

Ran a 20 foot hose from each one (to let the air temp cool down and water condense out) and into a Y connector at my high volume water trap http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=98904. | Ran a 20 foot hose from each one (to let the air temp cool down and water condense out) and into a Y connector at my high volume water trap http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=98904. | ||
| − | + | The output of the water trap has my air regulator and 50 foot of hose into the booth. | |
| − | I never ran out of air with my gun which needs 9.5 cfm @ 29psi. On long shoots I could hear the smaller air compressor turn on to keep up with the air demand but it normally only ran the larger compressor. | + | I never ran out of air with my gun which needs 9.5 cfm @ 29psi.

The beauty of this is I did not have to deal with supplying a 220V circuit for a larger system. | The beauty of this is I did not have to deal with supplying a 220V circuit for a larger system. | ||
